STICKY 'FLY-PAPER.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed August 4, 1910. Serial No. 575,448.

To all whom it may concern Be it known that I, JOHN H. Rusa, a citizen of the United States, residing at Tashington, District of Columbia, have invented new and useful Improvements in Sticky Fly-Paper, of which the following is a specification.

My invention relates to the manufacture of sticky fly paper and has for its object the production of sheets of such paper cut and creased in a peculiar manner so that they may be folded to constitute tent-shaped insect traps, the exposed sides of which are covered with sticky fly-catching material.

In practising my invention I am enabled to utilize all of a sheet of paper so that there is no waste in cutting and manufacture; and the completed traps when set up and ready for use are not easily collapsible nor easily overturned. These and other advantages incident to the invention will be apparent from a reading of the following specification and an examination of the ac.-

companying drawings in which preferred forms of my invention are illustrated.

Figure l is a plan view of a sheet of paper from which the blanks that I prefer to employ are formed, the lines on which the paper iscut and those on which it is scored for creasing and bending, being indicated. Fig. 2 is a perspective view of a pair of blanks or severed sheets, made as indicated in Fig. 1, as put up for sale.` Fig. 3 is a perspective view of the article. into which one of the said blanks is formed, Fig. 4 is a horizontal y sectional view taken on the line IV-'IV of Fig. 3. Fig. 5 is a view of the completed set up ready for use.

article suspended. Fig. 6 is a plan view of a sheet from which blanks of a form different from those illustrated in Fig. 1 are being formed, the lines of cutting and scoring being indicated. Fig. 7 is a perspective view of one of the traps made from a blank formed as indicated in Fig. 6.

In Fig. 1 of the drawings A represents a sheet of paper of indefinite length and proper width to form the blanks or severed sheets B, B. These are separated one from the other by cuts 2, 2, and are each of the form of a trapezoid, the non-parallel sides of which are inclined approximately to the parallel sides. As the inclination yof the successive cuts 2 is reversed, the entire V strip of paper may be utilized, and the blanks produced be identical in shape so,

they may be superposed as indicated in Fig. 2. Each blank is creased or scored adjacent to and parallel with its edges as indicated at 3, 3, 4 and 4,`and also alo-ng the transverse lines 5, 5', which radiate from the middle of the crease or score line, 4, that is parallel with the longer edge of the blank.

The creasing or scoring described divides that portion of the blank within the lines 3, 3, 4, 4 into three sections of triangular shape, designated respectively, b, b, b, and these sections are coated upon one face with a sticky fly-catching composition. Outside of the crease or score lines, 3, 4 and 3', are sections of the blank which are left uncoated, these being designated respectively, c, c and c. The blank is cut at the middle of its longer edge along the lines 6, -6, to form a section Z that is adapted to serve as a hanger for the folded blank, such hanger section being joined to the section ZJ of the blank at its apex. The cuts 6, 6, by which the hanger sect-ion d is formed, divide the unco-ated edge portion of the blank that is bounded by the crease or score line 4, into two portions which are designated e, c',

respectively. In one of these latter porl tions is formed a slit 7, and the other is cut to forma tongue S adapted to pass through the slit 7 as will be described.

The blanks B, formed in the manner indicated with the sections 6, b, o thereof coated with a flycatching substance, as indicated by shading in Fig. l, are placed together in pairs with their coated surfaces in contact, as indicated in Fig. Q, and laid out flat, in which condition they are put up for sale.

When the paper is to be used the sheets are separated from each other, and each is folded, along the lines 5, 5, to form a threesided tent-like body or pyramid, as indicated in Figs. 3 and 5. The edge sections e, e are thus brought together and united y by passing the tongue S through the slit 7.

The edge sections c, c', c are then foldedv out to constitute a bottom marginal flange which turns up slightly by reason of the several sections thereof being connected by the integral portions, f, f.

The hanger sectional which is located at the apex .of .the folded body is preferably turned back as indicated in Fig. 3 and serves either as a convenient means for picking up and handling the article, or suspending it, as indicated in Fig. 5.

llO

The body formed as described from a blank like that shown in F ig. l is sufficiently rigid to withstand any ordinary rough usage to which it might be subjected, it being well braced against collapse and having a wide supporting base.

The marg'inal flanges c, c', c serve not only to catch any of the sticky material applied to the surfaces o, o 7) which may run down such surfaces, but also operate to hold the body up from resting with one of its sticky faces upon the support upon which it may alight should it be accidentally overturned. The connected edges e, e and the hangerattachment Z also operate to prevent the article from resting with its sticky face in engagement with its support should it be overturned.

In Figs. 6 and 7 I have illustrated a form of the invention different in some of its features from that already described while having' many distinctive features in common therewith. As represented in F ig. G the blanks or severed sheets B are cut from a sheet of paper-A similar to that illustrated in Fig. l. The blanks B are preferably of equilateral triangular shape so that the entire strip of paper may be utilized and the blanks produced be of identical shape.

Each blank B is creased or scored adjacent to and parallel with two of its edges along the lines 3a, 8a, and parallel with its other edge along the line et, thus forming marginal sections cx, ZX and ex. The marginal section ex is divided into two portions by the hanger section d which is similar to the corresponding part of the blank heretofore described. A transverse crease or score line, 5X, starting from the crease or score line 4a adjacent to the hanger section (Z, divides the coated part of the sheetinto two sections, b", Z9". One portion of the marginal section, ex, has formed in it a slit 7, and the other portion, a tongue 8. The trap or completed article formed from the blank B is indicated in F ig. 7 and need not be further described, its method of setting up and the way it is used, being apparent from the drawings and the description already given.

rlhe two forms of inventions illustrated have the following features in common: They each comprise a blank having two nonparallel edges which are inclined te another straight edge, which may be designated the base edge, at similar, but reverse, angles, preferably at angles of 600. In each case this blank has an interior portion coated with a sticky fly-catching substance which is surrounded by marginal sections uncoated, and the coated portion of the sheet or blank is transversely creased or scored for folding the blank into the com pleted article or trap. The uncoated marginal portions of the blank are continuous except that the portion adjacent to the base edge is preferably severed at its middle, the cutting at this point being preferably utilized to form an integral hanger section like that designated CZ. The marginal sections of the blanks, except those parallel with the base edges, are turned outward, when the blanks are folded to form the traps, and constitute base flanges which are caused to turn up slightly, by reason of the several.

marginal sections being united by the integral portions designated This construction gives rigidity to the trap and effectually prevents accidental collapse thereof. In both forms of the invention the two portions of the marginal section adjacent to the base edge are brought together and united; and it will be seen that it is the similar faces of such sections that come together, that is to say, the two faces which may be designated as the outer or lower faces, to distinguish them from the faces on that side of the blank which is coated with the fly-catching material. These features of construction and karrangement which are common to the two forms of invention described, also distinguish them from other forms of fly traps formed out of sticky fly paper and with which I am acquainted.

I am aware that sticky fly paper has been shaped into cones and pyramids, and hence make no claim broadly to articles of this character. I believe, however, that I am the first to have produced an article such as herein described which possesses several distinct advantages over any of those which have been heretofore used or proposed. Among these may be mentioned the fact that the severed sheets or blanks from which the formed articles herein described are made can be easily and cheaply made by the use of automatic machinery and that in such manufacture there is no waste of the paper stock employed. The shaped body or structure formed from my blank is relatively rigid in construction and is adapted either to be suspended or to be set on a flat surface as may be desired, and when so set is not easily overturned, or, if overturned, is not liable to stick to the surface on which it may alight or rest,

I am also aware that articles constructed of paper, such as calendars, have been made with hanger sections formed from the same piece of material as the article itself by partly severing from the body of the material the section that is to serve as the hanger; and hence I lay no claim to being the inventor of an article, whatever its nature and character, provided with a hanger of this type. I, however, believe myself to be the first to have so cut the blank from which a iiy trap of pyramidal shape is formed with the hanger arranged at the apex of the trap when set up. To

secure this the blank is cut at its marginal edge to form the hanger-and not entirely within the confines of the blank as bounded by the marginal portions thereofwhich not only brings the hanger to the desired position when the blank is folded to produce the trap, but also makes it easier to reach the hanger portion to bend it out of the plane of the sheet of material constituting the trap, when it is to be used, than would be the case were it cut from the central part or body of the blank, which is the part that is covered with the sticky material.

lVhat I claim is l. A sheet of sticky fly paper, shaped to have a straight base edge and two nonparallel edges oppositely inclined to the base edge, the central portion of the sheet being coated with sticky material and such coated portion being transversely scored or creased for folding and there being a narrow marginal uncoated section along the base edge of the sheet, and a handling or suspending section separated from the marginal uncoated section and united with the central coated portion of the sheet and formed by cutting the said uncoated marginal base edge section at its middle, the two portions of the said uncoated marginal section on either side of the handling or suspending section being adapted to be brought together and united, whereby the said sheet will be folded on the said lines of scoring to form a tent-like structure.

2. A fly trap formed of sticky fly paper shaped into pyramidal form, the trap being formed with a hanger section at the apex of the pyramid integral with the central body portion of the sheet from which the trap is formed but severed from the marginal edge portion thereof, whereby it is adapted to be disposed at a convenient angle for being grasped or engaged by suspending means.

3. A sheet of sticky fly paper having a base edge and two non-parallel edges inclined thereto, the central portion of the sheet being coated and this coated portion being surrounded by marginal uncoated edge sections, and an integral handling section at the middle of the base uncoated section dividing the latter' into two parts, and united with the coated portion of the sheet.
